' A '7- To /V Ysl circle so as to cause the up and down move ment referred to. The specific mechanism shown in the drawings for accomplishing this urpose will now be described. A split colar surrounds the upper end of the lower tube section 18, and the ends of this collar at the split are continued outwardly to form two arms 31, 31. A screw 32 is turned through both arms, and has the effect of clamping the collar firmly to the tube 18. The outer ends of the arms 31 have pivotally connected thereto the lower ends of links 33, 33, and the upper ends of said links are pivotally connected. to the opposite side lates of a tail or projectionf34 extending from the nail slide 28 in a direction toward.

the -main portion of the implement. The tail or projection-34 is made '11 of the-two slide plates referred to, said pleltes spaced a slight distance apart and rigidly connected together. Arms 35, 35 are connected to oppo'sitesides of the hopper and extend rearwardly beyond the rear side of said hopper,

or closed by a curved block 44.

and are then bent inwardly toward each other, as indicated by the numerals 36, 36.

The inner edges thereof, however, do not meet, so that a space is left therebetween. To the rear sides of the inwardly bent portions 36 of the arms 35 are riveted plates 37, 37, which are angular in form so as to provide members 38 which extend rearwardly therefrom. The upper edges of the plates .37

,are provided with rounded sleeves 39, 39 in which are tightly fitted pins 40, 40. The two side plates of the tail or projection 34 have hubs 41, 41 extending therefrom. These hubs loosely surround the 'ins 40, so that said ins serve as pivots for t is turning of the nail slide. The upper edges of the two plates of the tail or projection are curved in corres ending arcs of a circle. The rear side of the iopper is also correspondingly curved, as indicated by the numeral"42, in order to register with the said curvature of the tail or projection, and thereby permit the latter to freely turn on its pivots. This curved portion 42 of the hopper is provided with an elongated slot 43, which communicates at its lower end with the elongated slot 26 in the bottom of the hopper. (See Figs. 13 and 14 of the drawings.) between the upper edges of the plates which form the tail or projection 34 is bridged over The for ward'end of this block terminates just in advance of the rear end of the upper slotted edge of the. slot of the nail slide 38, so as to leave a small opening 45.

It will be understood, and as will be seen from the drawings, that the nail slide 23 is continued rearwardly for a short distance through the elongated slot 1 3, and between the two luagnr the tail or projection 34, until it meets and registers will] the. slot of a nail runway 46, which runway is inclined A portion of the space I downwardly from the hopper. The forward or upper end of this runway is riveted between the members 38 of the plates 37, and the rear or lower end of said runway asses between and is riveted to the outward y eX- tending flanges 23, 23 of the plates 21, which lates before described are secured to the inner tube 20. The hopper mechanism is thereby made fast to said inner tube 20, and is caused to partake of the up and down movement of which said tube is capable. An upwardly extending tube 47 has a threaded connectionnt its lower end with the upper reduced threaded end of the inner tube seciipn 20. It will be evident from the constructio "thus far described that when the lower end of the outer-tube section 18 is placed against a roof or other surfac into which the nails are to be driven, and a down pressure eX- aerted on the tube 47, the inner tubrl section 20 is thereby caused to move downwardly until t e lower edges of the lates 21 contact with the lower bordering edge of the rectangular opening 19 of the lower outer tube section 18, when of course further movement of said tube is prevented. This down movement will necessarily cause a like movement of the nail hopper, by reason of the rigid connection between said hopper and the inner tube section 20 formed by the nail runway 46. As the ho per thus moves downwardly, an upward pus 1 is-exerted on the links 33, 33, and consequently an upward force is exerted by said links'against the tail or projection 34, and this necessarily causes the nail slide 28 to turn on the pivots 40 in a direction to swing downwardly the portion of the nail slide which is within the hopper. The limit of the, downward movement of the inner tube 20 is such that the nail slide will be turned downwardly only to such an extent as to cause its upper slotted edge to register or be on a plane with the edges of the slot 26 in the bottom of the hopper, and in this position the nail slide is inclined downwardly toward the front side of the hopper. (Sec'hig. 6 of the drawings.) The return upward movement of the tube 47 and consequently the lower inner tube section 20 is facilitated by a coiled spring 48. The lower end of this spring is seated in a cup 49 formed at the u per end of the lower tube section 18, and t 10 up er end of said spring is seated in a cup ed col ar 50 surrounding and rigidly secureri to the tube 47. On the up movement of the parts referred to, the hopper is necessarily caused to move upwardly, and this upward movement is continued until the upper edges of the lates 21 contact with the upper bordering er ge of the rectangular openlng 19. During the up movement of the hopper a downward pull is exerted on. the links 33,

pivots in a direction to bring said slide on a and hence the nail slide 28 is turned on its downward inciine toward the tube 18. this position its sinhtvd upper edge is bran to an inclined position toward the tube 18, and on a corresponding incline w the inciination i thv mummy, so that the Sim 0f the .this pm msc r-ons isis of n z-ing fitting: in :1 1'ecess 1n 'hv ngnmr 0nd or the nmm" Iuh s: i

far a SilOKt distmico, is conmved 01' rbund d assumed that previous from the outwardly slightly, as indicated by the l numeral 67, so as to accommodate the raised central portion of the cap.

When our device is employed in nailing generally under conditions where the caps are not employed, a collar'finot shown) is used with a hole large enough-to accommodate the jaws 62 as they descend.

The steps of the 0 er'ation of the median-- ism are as follows: TFhe hopper is filled with the nails which are to be fed to the runway and finally driven into the wood. It will be to the initial operation of' the device the nail slide 28 is in its raised position within the hopper. The lower end of the outer tube 18 is then brought into contact with the roof or other surface into which thenails are to be driven. A down movement is now exerted on the up wardly extending tube 47. This has the effect of turning downwardly ,the nail slide positionshown in Fig. 14, to the position siown in Fig. 13, .in which latter figure the slotted upper edge 29 of the slide is in registration with the slot 26 in the bottom of the hopper. It will be seenfrom the drawings that the bottom of the hopper not only inclines downwardly toward the outer side of the hopperbut said bottom may be said to consist of two 11. lf sections which also incline downwardly toward and to the cen-. tral slot 26 of the hopper. Therefore when the nail slide is swung to its lowered position the nails within the hopper freely slide down the inclined bottom of said hopper, and into the slot 29 of the slide, with the heads of the nails uppermost and resting on the upper bordering edges of the slot 29, as clearly shown in 13. The tube 47 i now raised, and this brings the nail slide into registration with the nail runway, as hereinbefore fully described. This causes the nails to slide 5 down the nail slide and into the slot of the runway. The raising of tube 47 also throws the nail forcing finger 56 out of operation, or in other words to the position shown in Fig. 8 of the drawings, while the inner guard finger 59 is turned to a position to intercept the nails, or to bridge over the opening 58-which leads to the bore of the inner tube 20, all as clearly shown in Fig. 8. The hammer is now raised, and following this the tube 47 again forced downwardly. This lattc'r down movement of said tube has the effect of throwing the inner guard fingers 59 from'the position shown inFig. 8 to the position shownin Fig. 9, while the nail pushing finger 56 is also turned from the position shown inFig. 8 to the position shown in Fig. 9, its free pointed en passing between two of the nails, so that when the ring 51 com letes its partial rotation in this direction t e advance nail which is engaged by the finger 56 is forced into the bore of the tube 20, as clearly illustrated in Fig. 10. The hammer is now brought down 'rearwardly mclined position in re 'reciprocablo with force, and first 62, 62 apart, and then contacts wit head of the nail, and drives the nail home. In all subsequent operations, that is, so long as there are nails in the hopper, it is only necessary to raise the implement from the roof or other surface, and this raising has the efiect of bringing the nail slide 28 back to its istration and wil furtherh the with the nail runway 46, more have the efiect of causing the inner guard finger 59 to assume the position shown in Fig. 8, that is the position in which itacts to prevent a nail assing into the bore of the tube 20. Following this, the lower end of the lower tube section 18 is placed against the roof or other surface, the hammer is raised, and the tube 47 again brought down, which has the effect of throwing the inner guard finger 59 from its Fig. 8 position to its Figs. 9 and 10 osition, and the nail pushing finger 56 from its Fig. 8 position to its Figs. 9 and 10 position, effect of feeding a nail into the bore of the tube 20'. The final step now is of course to bring. down the hammer forcibly.

What we claim as our invention is: 1. In nail feeding and driving meohan ism, the combination of nail driving mechanism having a lower stationary mcasmg portion and an interior tubular vertically reciprocable portion, a hopper provided with a slotted bottom and a slotted rear other, a runway inclined downwardl from the hopper to the nail driving mec ani'sm and rigidly secured at its upper end to the hopper and at its lower end to the vertically inner tube section, the-said runway having a slotted upper edge which extends to and communicates with a slot in the rear upright edge of said runway, a nail slide within the hopper and havin a slotted upper edge, and also provided wit a tail or rojection connecting, the rear wall of the hopper, with the main portion of the slide, said tail or projection mounted on a pivot arranged back of the hopper, and connecting mechanism between the lower incasing portion and the tail or projection, said connection being so constructed that when the inner tube section is forced downwardly the portion of the nail slide within the ho ,per is turned. downwardly in the are 0 a circle to cause its slotted upper edge to be bro'ught'into registra tion with the slot in the bottom of the hop.- per, and when said inner tube section is raised, the nail the are of a circle so as to cause its slotted 11 per edge to 0 me and in alinement with the slot of the runway. v
